[media] v4l2-tpg: ignore V4L2_DV_RGB_RANGE setting for YUV formats

2016-07-08T19:16:52+00:00

The V4L2_DV_RGB_RANGE_* settings are, as the name says, for RGB formats only.
So they should be ignored for non-RGB formats.

[media] siano: firmware buffer is too small

2016-02-16T11:29:13+00:00

Such error happens at the memcpy code below:

976					data_msg->x_msg_header.msg_length,
977					&coredev->data_download_done);
978
979			payload += payload_size;

The problem is that the Siano driver uses a header to store the firmware,
with requires a few more bytes than allocated.

	PCTV 77e (2013:0257)
	Hauppauge WinTV MiniStick (2040:5510)

[media] siano: remove get_frontend stub

2016-02-04T18:27:17+00:00

There's nothing at siano's get_frontend() callback. So,
remove it, as the core will handle it.

[media] b2c2: flexcop: avoid unused function warnings

2016-02-01T15:15:01+00:00

The flexcop driver has two functions that are normally used, except
when multiple frontend drivers are disabled:

drivers/media/common/b2c2/flexcop-fe-tuner.c:42:12: warning: 'flexcop_set_voltage' defined but not used [-Wunused-function]
drivers/media/common/b2c2/flexcop-fe-tuner.c:71:12: warning: 'flexcop_sleep' defined but not used [-Wunused-function]

This avoids the build warning by updating the #ifdef for flexcop_set_voltage
to the exact condition under which it is used. For flexcop_sleep, the
condition is rather complex, so I resort to marking it as __maybe_unused,
so the compiler can silently drop it.

Thus I'm replacing it. And, while being at it,
let's adapt some other (old) email-addresses as well.

[media] dvbdev: Add RF connector if needed

2016-01-11T14:19:25+00:00

Several pure digital TV devices have a frontend with the tuner
integrated on it. Add the RF connector when dvb_create_media_graph()
is called on such devices.

Tested with siano and dvb_usb_mxl111sf drivers.

[media] media-device: split media initialization and registration

2016-01-11T14:19:15+00:00

The media device node is registered and so made visible to user-space
before entities are registered and links created which means that the
media graph obtained by user-space could be only partially enumerated
if that happens too early before all the graph has been created.

To avoid this race condition, split the media init and registration
in separate functions and only register the media device node when
all the pending subdevices have been registered, either explicitly
by the driver or asynchronously using v4l2_async_register_subdev().

The media_device_register() had a check for drivers not filling dev
and model fields but all drivers in mainline set them and not doing
it will be a driver bug so change the function return to void and
add a BUG_ON() for dev being NULL instead.

Also, add a media_device_cleanup() function that will destroy the
graph_mutex that is initialized in media_device_init().

If media controller is enabled and mdev is filled, it should
ensure that the media graph will be properly initialized.

Enforce that.
